(C) 22 years
(D) 20 years
Answer: (A)
Explanation:
x y
Let the present ages of X and Y are and
X is 5 years older than Y
⇒ x = y + 5
………(1)
The total of the current ages of X and Y is 33 years
⇒ x + y = 33
⇒ y + 5 + y = 33
⇒ 2y = 28
⇒ y = 14
Present age of Y = 14 years
∴ Age of Y after 7 years = 14 + 7 = 21 years
Hence, the correct answer is Option (A)

(C) (3, 30, 12)
(D) (6, 219, 44)
Answer: (C)
Explanation:
The logic here is
43 + 3 = 64 + 3 = 67⟶ first number3 + 3 = second number
4 × (4 + 1) = 4 × 5 = 20⟶ first number × (first number + 1) = third number
Similarly,
33 + 3 = 27 + 3 = 30⟶ first number3 + 3 = second number
3 × (3 + 1) = 3 × 4 = 12⟶ first number × (first number + 1) = third number
∴ (3, 30, 12) are related in the same way (4, 67, 20) are related.
Hence, the correct answer is Option (C)

(A) 3 and 7
(B) 18 and 24
(C) 7 and 18
(D) 72 and 24
Answer: (B)
Explanation:
By Trial and Error method,
Option (A)
3 + 24 × 7 − 72 ÷ 18 = 58
3 + 24 × 7 − 4 = 58
3 + 168 − 4 = 58
167 = 58
Hence Option (A) is incorrect
Option (B)
7 + 18 × 3 − 72 ÷ 24 = 58
7 + 18 × 3 − 3 = 58
7 + 54 − 3 = 58
58 = 58
Hence, the correct answer is Option (B)

(A) EYC
(B) CUZ
(C) DPT
(D) BDH
Answer: (B)
Explanation:
The logic here is
EYC ⟶ E = 5, Y = 25, C = 3
CUZ ⟶ C = 3, U = 21, Z = 26
DPT ⟶ D = 4, P = 16, T = 20
BDH ⟶ B = 2, D = 4, H = 8
In the letter-clusters EYC, DPT, BDH, the values of all letters are either odd or even.
In CUZ, two letters are odd and one letter is even.
∴ CUZ is the odd one among the given letter-clusters.
Hence, the correct answer is Option (B)

(A) 5 years
(B) 3 years
(C) 6 years

Formula used:
SI=P×R×T/100
Calculations:
Let the sum be invested for T years
⇒ 2000 = (5000 × 10 × T)/100
⇒ 2000 = 500T
⇒ T = 20/5
⇒ T = 4 years
∴ The sum of Rs. 5000 earns a simple interest of Rs. 2000 in 4 years

Q. 73 Which of the following numbers is divisible by 3?
(A) 8765001
(B) 8703593
(C) 8703541
(D) 8703572
Answer: (A)
Explanation:
If a number is divisible by 3, then sum of the digits of the number should be multiple of 3
Sum of the digits of the number 8765001 = 8+7+6+5+0+0+1 = 27
Sum of the digits of the number 8703593 = 8+7+0+3+5+9+3 = 35
Sum of the digits of the number 8703541 = 8+7+0+3+5+4+1 = 28
Sum of the digits of the number 8703572 = 8+7+0+3+5+7+2 = 32
Clearly 27 is the multiple of 3, so 8765001 is divisible by 3
Hence, the correct answer is Option (A)

Q. 75 If tan2 x—3 sec2 x + 3 = 0, then the value of x(0 ≤ x ≤ 90 )∘ is:
(A) 30∘
(B) 0∘
(C) 60∘
(D) 45∘
Answer: (B)
Explanation:
tan2 x—3 sec2 x + 3 = 0 ,
= tan2 x − 3 (1 + tan2 x) + 3 = 0
= tan2 x − 3 − 3 tan2 x + 3 = 0
= −2 tan2 x = 0
= tan2 x = 0
= tan x = 0
= x = 0∘ (0 ≤ x ≤ 90 )∘
Hence, the correct answer is Option (B)
